Project Highlights

This project provided an excellent opportunity to develop a rich web application with an advanced graphical user interface using PrimeFaces, while improving performance and scalability through the use of the lightweight Spring framework.

It also allowed me to gain hands-on experience with several important and widely used technologies, including Maven for dependency management, Hibernate for ORM, and PrimeFaces for building modern user interfaces.

Additionally, this project introduced me to Agile development practices, particularly the Scrum methodology, which enhanced my understanding of structured teamwork, task planning, and iterative development.

Conclusion

This new version successfully integrated modern and innovative technologies such as Spring, Hibernate, Maven, and PrimeFaces to deliver a more secure, scalable, and high-performance POS back office application.
